Abstract

Die Erfindung betrifft einen Fahrzeugscheinwerfer mit einem Gehäuse, einer das Gehäuse abdeckenden lichtdurchlässigen Abschlussscheibe (38), zumindest einem in dem Gehäuse angeordneten Reflektor für Fahrlicht, zumindest einem zweiten in dem Gehäuse angeordneten Reflektor (12) für Blinklicht, zumindest einem dritten in dem Gehäuse angeordneten Reflektor (14) für Positionslicht, den Reflektoren jeweils zugeordneten Lichtquellen (16,18) und einem die Reflektoren in Abstrahlrichtung umgebenden rahmenartigen Abdeckteil (10), welches erfindungsgemäß mehrere Bereiche mit unterschiedlichem Reflexionsgrad aufweist, von denen die größeren Bereiche (20) eine Oberfläche mit einem niedrigen Reflexionsgrad und die kleineren Bereiche (22), von denen zumindest ein erster kleinerer Bereich (24) lichttechnisch der Lichtquelle (16) für Blinklicht und zumindest ein zweiter kleinerer Bereich (26) lichttechnisch der Lichtquelle (18) für Positionslicht zugeordnet ist und die das von den jeweiligen Lichtquellen (16,18) auf sie auftreffende Licht in Richtungen umlenken, die in einem großen Winkel im Bezug auf die Hauptabstrahlrichtungen (HR) der Reflektoren (12,14) liegen, eine Oberfläche mit einem hohen Reflexionsgrad aufweisen.
